The Right Fit

Postby Rotbone » Tue Sep 06, 2011 5:59 pm

Hello, I recently purchased a PC for my son from CyberPower. Long story short, I am not sending it back a second time. They are the worst I have every dealt with.

What I need to do is replace the bad water pump they installed. It stopped working once, sent back. Stopped working again. I want to make sure I am buying the right fit for this system. I want to make sure the pump I buy will handle 1 CPU block and 2 GPU blocks. I am an experienced computer tech, but I have been out of the loop for about 5 years now so I don't know much about the water cooling systems. I have drained the system and I am now ready to replace the junk. Please look at the PC specs and give me your input as to what size pump I need as to the flow rate, head pressure etc. etc.

Thank you

A dual pmp-400 or pmp-450 unit would be best of course as overkill on cooling is always beneficial if you can afford it. However even a single PMP-400 or PMP-450 should be able to handle what you have listed just cooling the CPU and 2GPUs.

I have 2 PMP-400 pumps in series in a Koolance RP-401X2. At first I ran just a CPU block (Koolance 370) and could get 1gpm flow rate when running the pumps at 8v.

I then added a single EVGA 590 Hydro Copper and now have to run the pumps at max (12.7v via Koolance TMS-200) to get 1gpm.

I find the hydro copper blocks cool well but are very restrictive. I do not know what the effects of two of them would be on the flow rate of my loop.

As it stands things still stay nice and cool when I run the pumps lower at 9v, I am going more for a quiet system than being able to max my overclocks with water cooling.

Given the opportunity I may have gone with a pair of PMP-450s and the RP-452X2 reservoir if I knew those cards would affect flow rates this way.
